Update -maltivec and -mvsx options to only enable their oldest instructions.
Currently, the -maltivec and -mvsx GAS options enable *all* of the altivec and vsx instructions respecitively that have ever been added. This is in constract to GCC's -maltivec and -mvsx options, which only enable the oldest (ie, first) set of altivec and vsx instructions. This patch changes GAS to mimic GCC's behaviour with respect to -maltivec and -mvsx and it solves a problem with trying to assemble the lxvx instruction which is different between POWER8 and POWER9. opcodes/ * ppc-dis.c (ppc_opts) <altivec>: Do not use PPC_OPCODE_ALTIVEC2; <vsx>: Do not use PPC_OPCODE_VSX3; gas/ * testsuite/gas/ppc/altivec2.d (as): Use the -mpower8 option. (objdump): Use the -Mpower8 option.
